Abstract
A new and improved pipeline coupling apparatus is disclosed. This apparatus incorporates an elongate support member having the form of an I-beam where the flanges of the I-beam serve as a guide for a traveling carriage. The traveling carriage is urged along the I-beam by means of a hydraulic cylinder and piston rod. The traveling carriage centers a pipe. It positions the coupling and forces the pipe into the coupling. The coupling itself is supported for sliding movement by a free moving carriage beneath the I-beam.

An apparatus for achieving underwater connection of a first pipe which is telescoped into a second pipe, comprising:
- an elongate frame member;
- means for releasably clamping said frame member parallel to a first pipe;
- second means for clamping said elongate frame member relative to a second pipe, the first and second pipes being parallel to one another and axially spaced apart;
- moving means carried on said elongate frame member and connected between said first and second clamp means for pulling one of said clamp means toward the other to move the first and second pipes toward one another and telescoping connection with one another.
